OIL-BURNER. 7

Specification of Letters Patent.

Patented Aug. 16, 1910.

Application filed September 22, 1909. Serial No. 518,90a.

To all whom it may concern:

Be it known that I, Gnonon F. MOODY, a citizen of the United States, anda resident of Altoona, in the county of Blair and State of Pennsylvania,have invented a new and Improved Oil-Burner, of which the following is afull, clear, and exact description.

This invention relates to burners of a class in which fuel-oil and airare heated and mixed, forming a finely subdivided fuel that is burnedfor heating purposes; and has for its object to provide novel details ofconstruction for an oil burner of the class indicated, which is highlyeffective as a means for welding metal parts together, is economical inthe consumption of liquid fuel, affords a hydrocarbon vapor that issuesfrom the burner in blue jets of flame, and is adapted for useful effectas a heating medium that may be utilized for difi'erent purposes.

The invention consists in the novel construction and combination ofparts is hereinafter described, and defined in the appended claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views. 1

Figure 1 is a partly sectional plan view of the improvement; Fig. 2 is aside view of the same; and Fig. 3 is an enlarged transverse sectionalview, taken substantially on the line 33 in Fig. 2.

In the drawings 5 indicates a mixing chamber, preferably cylindrical inform, that may be a metal tube of proper dimensions. An air jet-pipe 6,is held centrally and longitudinally within the mixing chamber 5,preferably by means of three clamping screw bolts 7, that are screwedthrough tapped perforations in the wall of the mixing chamber equallydistant from each other, and near the extremity of the pipe that iswithin said chamber; and as shown in Fig. 1,

this end of the air pipe 6, terminates in a jet nozzle 0. Asupplementaryair blast pipe 8 is held parallel with the pipe 6, near the normallylower side of the mixing chamber 5, by a plate metal. clamp 9, locatednear the rear end of the mixing chamber.

The air jet pipe 6, near its rear end, is bent at an angle toward thesupplementary air blast pipe 8, and secured thereto by a T-fitting b, asbest shown in Fig. 2., and from said fitting the air blast pipe 8 isextended to a source of air supply under proper pressure. In the pipes 6and 8, valves 6 and 8 are respectively introduced, for control of theair forced therethrough. The remaining end of the supplementary airblast pipe 8 is extended in front of the mixing chamber 5, and may bebent so as to form an offset 0, therein, which will direct the aircurrent passing therethrough in a proper direction for useful effect.

An oil feed pipe 10 is supported from the air jet pipe 6, and air blastpipe 8, by a clamp 11, that embraces these pipes, thus disposing the oilfeed pipe above the air jet pipe at the rear portion of said oil feedpipe. At a suitable point forward of the clamp 11, the oil feed pipe isprovided with two branch pipes 12, which extend laterally in oppositedirections, as shown,in Fig. 1, and then forwardly parallel with eachother, at opposite sides of the mixing chamber. The forward ends 12 ofthe branch oil pipes 12-, are extended toward each other at a rightangle, through the wall of the mixing chamber 5, and their inner ends 0,e, terminate in like jetnozzles that are spaced apart opposite eachother. The jet nozzle a that is on the forward extremity of the air pipe6, is disposed near to and between the jet nozzles c, c.

The rear end of the oil feed pipe 10 is extended toward and connectedwith an oil supply under pressure, and in said pipe near the valves 6 8a valve 10 is introduced which serves to graduate the feed of the oilfor spraying from the jet nozzles c, e.

While the improved oil burner may be employed as a heating medium fordifferent purposes, its preferred use is for welding joints on a framefor a locomotive engine while in place thereon. To this end, a temporaryinclosing wall is built around the portion of the frame which is to bewelded, and the heating device is supported thereat, in proper positionfor directing a blast of flame directly upon the exposed joint that isto be welded. The spraying jets of oil that are now projected towardeach other from the nozzles e, e, are met by a forcible air j at issuingfrom the nozzle a.

The mixed currents of atomized oil and atmospheric air flow from theforward end of the mixing chamber 5, and when ignited burn fiercely witha blue flame, and as a further supply of air may be found advantageous,for blending with the air and oil jets, a plurality of perforations gare formed in the mixing chamber near said jets. The forward portion ofthe supplementary air blast pipe 8 is so relatively positioned, that thecurrent of air issuing therefrom will be adapted for directing the flameat the front end of the mixing chamber, into contact with the materialto be welded, and thus control the welding operation.

It is found in practical operation of the improved heating device, thatthere is a great economy effected in the consumption of fuel oil, that amoderate air pressure is sufficient for highly effective service, andthat a perfect Weld is produced in a comparatively rapid manner.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent:

1. An oil burner comprising a mixing chamber, an air supply pipe at oneend of the chamber and extending along below the same and having anupwardly offset portion at the opposite end of the chamber, said pipehaving a branch extending into the chamber, a fuel supply pipe adjacentthe air supply pipe, said pipe branching adjacent to the chamber, thebranches extending alongside the chamber, and each having a lateralnozzle extending into the chambe at right angles to the inner branch ofthe air supply pipe and having the inner ends adjacent thereto, meansfor supporting the air pipe in the chamber, clamps connecting the fuelsupply pipe with the air supply pipe and valves controlling the saidpipes.

2. An oil burner comprising a mixing chamber, an air supply pipe at oneend of the chamber and extending along below the same and having anupwardly ofl set portion at the opposite end of the chamber, said pipehaving a branch extending into the chamber, and a fuel supply pipeadjacent the air supply pipe, said pipe branching adjacent to thechamber, the branches extending along side the chamber, and each havinga lateral nozzle extending into the chamber at right angles to the innerbranch of the air supply pipe and having the inner ends adjacentthereto.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
